IMPROVED APPLICATION OF RUDDERS T0 SPINDLE-SHAPED HULLS.

VSpecification forming part of Letters Patent N0. 58,743, dated October 9, 1866.

To all whom t may concern:

Be it known that we, WrLLlAM LOUIS WI NANS, ot' London, England, and THOMAS WL NANS, of Baltimore, United States ot' America, have invented Improvements in Adapting,` Screw-Propellers for Propelling Ships orVessels for Ocean Navigation; and we do hereby declare that the following' is a full and exact description ot' our said invention.

Our present invention of improvements relates to adapting' rudders to a spindle-shaped hull, such as was invented by Ross and Thomas Winans and for which Letters Patent were granted to them 26th October, 1858, No. 21,917.

This invention consists in the arrangement of the rudder as applied to propellers of spindle-shaped hulls.

The propeller shaft or shafts may be placed in any suitable posit-ion in the vessel, at or below the center line or line of tiotation, and may be actuated by the same or by separate engines, and the propellers may be driven in the same or in opposite directions.

The invention likewise consists in similar adaptations and combinations ot propellers to or with a spindle-shaped hull having,` a flat, or nearly liat, upper deck with bulwarks, railing, or cabin or cabins, with upper or hurricane deck, similar to that invented by us, and for which we have applied for Letters Patent.

In the accolnlmnying drawings, Figure 1, Sheet I, is a side elevation ot' part ota spin- (lle-shaped vessel, with a screwpropeller, a, adapted near to one end. Fig'. 2 is a front view of the same.

The propeller may be of the Ordinar)v canstruction7 and is mounted on one end ot' the shaft b, which may be, it desired, provided at the other end with a similar propeller. The

projecting end of the shaftb is supported in bearings in the brackets c c, which are secured to the pointed end of the vessel.

The rudder d d is placed in front of the propeller, and is made double-that, is there are two plates, one on each side of the propellershaft. i

Fig. 3 is aside elevation ot' part of a spindle shaped vessel, to which two propellers are adapted at the same end of the vessel. Fig. 4 is a front view of this part.

It will' ot course be obvious that in combination with these two propellers one or two propellers mayY be adapted to the opposite end ofthe vessel, so that the vessel may have two, three, or four propellers.

When there are two propellers at the same end ot' the vessel the rudder which is placed in advance is situated between the two propellii'lg-shafts, which are supported by bracketarms, as in the former instance.

Having now described our inventionof improvements in adapting serew-propellers for propelling ships or vessels for ocean naviga tion, and havingl explained a manner ot' carry ing the same into et't'ect, we claim as our invention- 1. The rudders d, placed between the brackets c and the midship ot the spindle-shaped hull, its leaves occupying` respective sides of the single propeller-shaft, substantiallT as described, for the purpose specitied.

2. The central rudder, d, placed between the brackets c and the midship ot the, spindleshaped hull, when arranged with more than one propeller-shaft, substantially as described, t'or the purpose specitied.

In witness whereot1 we, the said WIILLIAM LoUIs WINANs and Tuomis Winans, have hereunto set our hands and seals the 20th datr of January, 1866.
